How To Learn Surface Mount Soldering

There are two kinds of soldering PCBs: through hole and SMD. Through hole uses components with leads, which are threaded through holes (hence the name) in the PCB and then fixed to the PCB with solder. SMD uses Surface Mounted components. That is, very miniaturized components that are soldered onto the surface of the PCB, without using leads.
Due to the small size of the components it is at first much harder to solder than for classic through hole parts. To save you from the misfortunes of failed projects, there are practice kits available. We will assemble one such example today and I will try to teach you the basics of SMD soldering as well as some more advanced tricks.

"You can see the tiny resistors here." We absolutely cannot. Great job, I have no idea how you managed to get those on so well.

@root42 3 года назад

Lots pf practice. And this is what these kits are great for!

Ive been wanting to learn how to solder and this kit with your tutorial helped me so much. Thank you sir!

@Sparkingacrossamerica Год назад

Thank you for explaining. I’m new to this and you helped me out a ton

Nice to know about these practise kits (Y)

I watched your vid multiple times. After receiving my 3 test boards I was ready! The only thing I discovered was D1 in the center of the board the LED green tip points down not up. After corrected my second board worked fine. I only had red LEDs though no blue. As you did mention for the 0402 parts, I also fluxed and pre-tinned the pads for the center diodes, and chips. That was a lot easier than doing each point by hand.

Good job! They throw in whatever parts they have I think. So having different color LEDs is no surprise.

Not sure what country you live in but I live in the US and I can still buy leaded solder. Great video.

@cobra5586 2 года назад

In Germany and EU it is forbidden. But several online shops offer leaded solder, so you can also buy this solder even in Germany or countries in EU.

Yes well, I liked, I ordered it. Thanks.

You’re welcome!

here in canada you can still buy leaded solder, i strongly prefer leaded solder

As it so happened I ordered the same practice kit, but i found soldering with tin very tricky. So i tried with solderpaste and put a tiny blob on the pads, and that would stick doen the component, then just heating the edge of the pad was enough to heat the pad, solderpaste and componen to get a nice solder joint. The heated solderpast had enough surface tension to pull the component into alignment. Then it was just a matter of heating the other side. Oh , and the 4017 and 555 were much easier to solder than the other components.

@root42 6 месяцев назад

Sounds about right. Solder paste of course comes with quite a bit of flux, so it should making soldering quite easy. It’s all mostly practice, practice, practice. No matter what you use.

schöne Karte, jetzt habe ich sie endlich mal gehört. Und ich dachte die coolste Karte wäre die Auzentech Prelude. Gruss aus Kerpen

Hi, thanks for it. Do yoou have this paper . With components values.?? I have dificult to identify each one.

@root42 6 месяцев назад

No... but you can measure with a multimeter or one of the cheap component testers. The resistors have values on them, the caps need to be measured.

@premierdancex7590 6 месяцев назад

What kind of battery pack is that that you’re testing it with? I finished the soldering but don’t know what battery tool to use to test it out

@root42 6 месяцев назад

I used a 4xAA battery holder with NiMH batteries. This gives about 5V when they are full charged. With Alkaline batteries you should probably use 3xAA. You could also solder a USB connector to the pads and use a power bank.

I started this today and I've lost one of the resistors already. If not for this video I wouldn't know what's what tbh

@vincent.416 7 месяцев назад

Recieved mine today from Amazon and there is no clear indication of which part goes where. All components are thrown in a ziplock and not labeld. Instructions are unclear and have been translated. Tutorials online all have different rated resistances so can't even follow along. Have to send it back.
